Voiceprint is a psychological horror game where the monster hunts you using your own voice cloned in real-time by ElevenLabs. WHAT IT DOES You explore an abandoned radio station that mysteriously kept broadcasting after closing eleven years ago. Halfway through, the game asks you to speak into your microphone for fifteen seconds. ElevenLabs clones your voice instantly. Within moments, the monster starts whispering at you from the dark in your own voice. "I'm right behind you." "Don't turn around." Players hear themselves say things they never said. HOW WE USED ELEVENLABS (5 APIs) - Instant Voice Cloning clones the player's voice live, mid-game, then uses the cloned voice ID to generate monster whispers - Text-to-Speech (Cedric voice, Eleven v3) cinematic narrator throughout - Sound Effects API ambient drone, footsteps, monster sounds, distant whispers, transition impacts - Music API original 60-second horror score for the trailer - All routed through Vercel serverless functions to keep API keys server-side HOW WE USED ZED Built end-to-end in Zed using its AI agent panel for rapid iteration on the Three.js scene, voice-cloning audio routing, monster AI, and shader pipeline. Zed and ElevenLabs are both built into the world as in-game sponsor posters pristine on one wall, defaced with red spray paint on another. Worldbuilding, not branding. WHAT MAKES IT SPECIAL This game cannot exist without ElevenLabs. Voice cloning isn't a feature added on top it's the entire mechanic. Last year's Supernormal made you talk to ghosts. This year's Voiceprint makes the ghost talk back, in your voice. Built in 4 days. Runs in any browser. Microphone required. Live demo: voiceprint-alpha.vercel.app
